PHP MYSQL将结果放入一个表中
我有一个返回以下内容的PHP/MySQL查询：PHP MYSQL将结果放入一个表中,php,html,mysql,for-loop,Php,Html,Mysql,For Loop,我有一个返回以下内容的PHP/MySQL查询： array ( 'name' => 'Jess', 'month' => '2020-03-31 12:28:00', 'count' => '1', ) array ( 'name' => 'Bob', 'month' => '2020-04-31 12:28:00', 'count' => '2', ) array ( 'name' => 'Tom', 'month' => '2020-05-31

只是一个快速更新。通过下面的代码，我成功地得到了我想要的

现在是学习如何使用JOIN
s$tr.=”的时候了$本月。“
将此更改为$tr.=”$本月。"";嗨，Prateik，这似乎并没有解决问题：嗨，Cid，你能扩展JOIN的吗？我完全支持学习，所以如果你能推荐我应该在哪里使用连接，那么我将开始学习。。。感谢在循环中形成数据库查询通常被认为是一种不好的做法。不要先选择用户，然后再为循环中的每个用户选择数据，而应该首先在一个查询中将所需的所有数据连接在一起。
